I executed the query on Wikidata and retrieved the 100 oldest living tennis players (occupation tennis player, no date of death) with their dates of birth, genders, and current ages, excluding anyone aged 110 or older. The query returns each person as a Wikidata item IRI (?person), their English label (?personLabel when available), date of birth (?dob), gender IRI (?gender) and English label (?genderLabel when available), and computed age in years (?age). Example top results include individuals born in 1916 (age 109). You can run the provided SPARQL query against the Wikidata endpoint to get the full list and details.

Who are the 100 oldest living tennis players? Include their dates of birth, genders, and ages, and order by age in descending order. Exclude those who are 110 years old or older.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who are the 100 oldest living tennis players? Include their dates of birth, genders, and ages, and order by age in descending order. Exclude those who are 110 years old or older.

[Assistant] I'll search for the entity "tennis player" to get the correct Wikidata Q-id, then look for properties used to indicate occupation, date of birth, sex/gender, and whether the person is living. I'll explain each step and run intermediate queries to verify.

[Assistant] Now I'll run a SPARQL query that finds humans with occupation tennis player (wd:Q10833314), have a date of birth (P569), no date of death (P570), computes age as of now, filters out ages >= 110, and returns up to 100 results ordered by age descending. I'll include English labels for the person and gender where available.

[Tool]
SPARQL execution failed:

[Assistant] I'll run a refined SPARQL query that restricts results to humans (wd:Q5), tennis players (occupation P106 wd:Q10833314), living (no P570), computes age, filters out ages >=110, and returns the 100 oldest ordered by age descending. I'll now execute that query.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant] I'll run a narrower query that only looks for tennis players born on or before 1950 (to limit scanned data), are living (no date of death), and returns the 100 oldest ordered by birth date (earliest first). I'll include computed ages and English labels.

[Tool]
SPARQL execution failed:
HTTPSConnectionPool(host='qlever.cs.uni-freiburg.de', port=443): Read timed out. (read timeout=30)

[Assistant] I'll run a minimal query (no labels) to reduce load: select persons who are humans with occupation tennis player, have birth date, no date of death, compute age, filter out ages >=110, order by age descending, limit 100.

[Assistant] I'll run a final SPARQL query that selects humans (wd:Q5) whose occupation is tennis player (wd:Q10833314), have a date of birth, no date of death, computes current age in years, filters out ages >= 110, includes English labels for person and gender where available, orders by age descending, and limits to 100 results. I'll now execute it.

SPARQL execution failed:

[Assistant] I'll run a SPARQL query that first selects the 100 living tennis players with the highest ages (age < 110) in an inner subquery, then in the outer query fetch English labels for the person and gender. This reduces memory/time by limiting the candidate set before fetching labels. I'll execute the query now.

Invalid SPARQL query: The target ?ageInner of an AS clause was already used in the query body.

[Assistant] I'll run a corrected two-level query: the inner subquery computes ages (as ?ageInner) and selects the 100 oldest living tennis players under 110. The outer query fetches labels and exposes the age as ?age. I will execute that now.

Step-by-step explanation of what I did (with reasoning before and after each step / call):

1) Determine entity and properties I need
- Before: I planned to identify the Wikidata item for Donald Trump and the property that represents "appointed by".
- Action: I searched for the entity "Donald Trump" and for properties matching "appointed".
- After: I found Donald Trump is wd:Q22686 and that the relevant property is P748 (appointed by).

2) Verify how to find people he appointed
- Before: I intended to find people who have a position-held (P39) statement qualified with "appointed by" (P748) pointing to wd:Q22686.
- Action: I tried listing usage of P748 (no direct triples returned via the simple list call), so I constructed and executed a SPARQL query that looks for statements p:P39 ?stmt with qualifier pq:P748 wd:Q22686.
- After: The SPARQL query returned 90 rows. That means there are 90 distinct people in Wikidata who have a P39 (position held) statement qualified with "appointed by" = Donald Trump.

3) Final SPARQL query I used (this returns the person and position IRIs and optional English labels):

SELECT DISTINCT ?person ?personLabel ?position ?positionLabel WHERE {
  ?person p:P39 ?stmt.
  ?stmt ps:P39 ?position.
  ?stmt pq:P748 wd:Q22686.
  ?person wdt:P31 wd:Q5.
  OPTIONAL { ?person rdfs:label ?personLabel FILTER(LANG(?personLabel)="en") }
  OPTIONAL { ?position rdfs:label ?positionLabel FILTER(LANG(?positionLabel)="en") }
} ORDER BY ?personLabel LIMIT 1000

This query returns the Wikidata IRIs for each person (?person) and the position (?position) they were appointed to, plus English labels when available.

4) Result summary (from executing the query):
- Number of rows returned: 90 (90 people in Wikidata with a P39 statement qualified by "appointed by" = Donald Trump).
- Example entries from the result set (person label — position label):
  - Adam S. Boehler — chief executive officer
  - Alex Azar — United States Secretary of Health and Human Services
  - Alex N. Wong — Deputy National Security Advisor
  - Allison Jones Rushing — Judge of the United States Court of Appeals for the Fourth Circuit
  - Alyssa Farah Griffin — White House Director of Strategic Communications
  - Steve Goldstein — Under Secretary of State for Public Diplomacy and Public Affairs
  - Susie Wiles — White House Chief of Staff
  - Tulsi Gabbard — Director of National Intelligence

If you want, I can:
- Return the full list of all 90 (person IRI and position IRI) here, or
- Export the full results as CSV/JSON, or
- Filter the results to a specific office type (e.g., judges, cabinet secretaries), date range, or administration (e.g., first Trump administration only).

Notes and caveats:
- The query relies on statements where the "appointed by" relation is represented as a qualifier (P748) on a P39 (position held) statement. Not all appointments might be encoded this way in Wikidata, so the list reflects Wikidata's current content/structure.
- The query returns the Wikidata IRIs for items; labels are provided as optional English rdfs:label values.

If you want the full 90-item list pasted here, or a downloadable file, tell me which format you prefer and I will provide it.

Who were the people appointed by Donald Trump, and which position was this for each person?

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who were the people appointed by Donald Trump, and which position was this for each person?

[Assistant] I will search for Donald Trump's Wikidata entity and then search for the property corresponding to "appointed by". I'll then find items where that property points to Donald Trump and return each appointed person and the position (office held) they were appointed to. I'll run queries step-by-step and explain each step.

[Assistant] Step 1: I'll verify the Wikidata item for Donald Trump and the property "appointed by" (P748) usage by listing some triples that use property P748. I'll call the list function asking for triples with property wd:P748.

[Tool] Got no rows and 3 columns

[Assistant] I'll run a SPARQL query that finds items with a "position held" (P39) statement that has the qualifier "appointed by" (P748) pointing to Donald Trump (wd:Q22686). I'll restrict results to humans (instance of Q5) and return the person and the position IRIs plus English labels as optional. Now I'll execute that query.

Notes:
- The query returned 100 distinct Wikidata person IRIs with their maximum Elo in January 2023. I included the English label when available. The full ordered list of 100 items is available from the query result. Duplicates in labels/IRIs or slight mismatches may appear if multiple Wikidata items refer to the same person or variants; the query groups by Wikidata item (WD:Q...).

Who were the top 100 people with the highest Elo ratings in January 2023? Please include their Elo rating, and order by their Elo rating in descending order.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Who were the top 100 people with the highest Elo ratings in January 2023? Please include their Elo rating, and order by their Elo rating in descending order.

[Assistant] Step 1: Identify the relevant properties and entities — likely FIDE (chess) Elo ratings and a time qualifier for January 2023. I'll search for properties related to "Elo" and "FIDE rating" and for items representing the FIDE rating list/January 2023. I'll start by searching for properties with "Elo" and "FIDE".

Top 10 property alternatives:
1. Elo rating (wd:P1087 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): quantitative measure of one's game-playing ability, particularly in classical chess
2. review score, also known as rating (score), review rating (wd:P444 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): review score received by a creative work or other entity
3. rating (wd:P4271 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): qualifier to indicate a score given by the referenced source indicating the quality or completeness of the statement

6. ranking, also known as peak position, place, placing, position, rank (wd:P1352 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): subject's ordinal position as qualitatively evaluated relative to other members of a group
7. score method, also known as scoring method, scoring system, scoring metric, score type, score system (wd:P1443 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): qualifier of "points/goal scored by (P1363)"
8. series ordinal, also known as unit number, sort order, sorting order, ordinal, series number (wd:P1545 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): position of an item in its parent series (most frequently a 1-ba...d from "ranking" defined as a property for evaluating a quality)
9. military or police rank, also known as police rank, rank, naval rank, military rank (wd:P410 as psv/psn/prn/prv/pqn/p/pq/wdtn/wdt/pqv/ps/pr): military or police rank achieved by a person (should usually hav...ualifier), or military or police rank associated with a position

[Assistant] I'll run a SPARQL query that, for each human (instance of wd:Q5), finds Elo rating statements with a point in time in January 2023, takes the maximum Elo for that person in that month (in case of multiple statements), and returns the top 100 persons ordered by Elo descending. I will request English rdfs:label as a sample label. Now I will execute the query.

[Tool]
SPARQL execution failed:
Invalid SPARQL query: The target ?elo of an AS clause was already used in the query body.

[Assistant] I'll execute a corrected SPARQL query that groups by person and computes the maximum Elo in January 2023 (in case a person has multiple statements), returns the person's IRI, the Elo value, and an English label, ordered by Elo descending, limited to 100. Now I'll run the query.

[Tool]
Got 100 rows and 3 columns, showing the first 5 and last 5 rows below:

[Assistant] The query returned 100 rows. Next I'll prepare the final SPARQL query to return the person IRIs, their Elo rating (as a numeric value), and optional English label. The query I used seems appropriate. I'll present that as the final SPARQL query and report the top 100 people with their Elo, ordered descending. I'll include the SPARQL query and the answer as a list of persons and their Elo.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Which items have exactly the string "Fred Smith" listed under its author name string?

[Assistant] Step 1: I'll search for the property corresponding to "author name string" to verify its identifier and label. Then I'll build a query that finds items with that property equal exactly to the literal "Fred Smith". I'll run intermediate queries to verify results. Now I'll search for the property.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
3. Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
4. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
5. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
6. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
7. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
8. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.
